A province has the region Holy Site attached, therefore it doesn't hold dynasty cards, and the region reacts to negate the destruction of the province.
When will the province be refilled? The logical answer would be immediately after the region's destruction, but the rules only cover refilling provinces after a card leaves the province; there's no word about refilling in response to any other situation. (A similar paradox might also occur with Hidden Moon Dojo and discarding effects during the owner's action phase)
[url=http://rules.l5r.com/Areas_of_the_game#The_provinces_.28out_of_play.29] SE CR:[/url] When a card leaves a province and the province then holds fewer than its maximum number of cards, effects triggered by the card leaving the Province or entering play resolve first (including effects of Events that resolved from that Province). Then, if the Province still holds fewer than its maximum number of cards, it is refilled with a face-down Dynasty card from the top of the Province’s owner’s deck, unless something else has refilled it.

Refill immediately unless some effect prevents it.

Regarding this
I'm pleased with the answer but I'm still concerned. Which rule is the basis for the answer? I haven't found any rules covering this situation of a province being empty without any dynasty card leaving it; and regions in play aren't "in" a province so they can't "leave" it. If there's one, please direct me to it; otherwise, I'd ask it to be fixed in either version of the CR.

Celestial Edition rulebook, page 20: "If a province is ever without a card, refill it immediately with a face–down card from the top of your Dynasty deck."
